Keyword density is calculated by dividing the number of times a keyword appears on a page by the total number of words and multiplying by 100. For example, a phrase appearing 10 times in a 1,000-word page would have a keyword density of 1%.

However, there is no ideal keyword-density percentage that businesses should target for modern SEO. Repeating an exact phrase simply to reach a particular density can make content unnatural and may reduce quality. Search engines can understand related concepts, entities, synonyms, and context far beyond exact keyword repetition.

A better approach is to use the primary topic clearly in important locations—such as the title, main heading, introductory copy, and relevant subheadings—while answering the subject comprehensively in natural language. Related terminology should appear because it improves the explanation, not because a formula requires it.

This is part of effective on-page SEO. Start with sound keyword research, understand the searcher’s intent, and create the best useful answer rather than optimizing toward a density score.

An SEO audit is a systematic evaluation of the factors affecting a website’s organic search visibility and performance. A comprehensive audit examines technical health, content and keyword alignment, internal linking, site architecture, backlinks and authority, competitive performance, indexation, and measurement.

The purpose is not simply to generate a long list of errors. A useful SEO audit identifies what has happened, the site’s current condition, the issues constraining performance, and which actions should be addressed first based on likely business impact.

Technical analysis may include crawlability, redirects, canonicals, duplicate content, broken links, sitemaps, page performance, and indexation. Content analysis examines search intent, keyword targeting, quality, topical coverage, cannibalization, and internal links. Competitive analysis helps determine whether the website has enough authority and content depth to compete.

An audit should ultimately produce a prioritized roadmap. Learn more about technical SEO, competitive analysis, and Webolutions’ SEO services.

A local citation is an online mention of a business’s identifying information, typically its name, address, and phone number, often called NAP information. Citations can appear in business directories, chambers of commerce, industry associations, local publications, mapping services, social profiles, and other trusted sources.

Citations help search engines and customers verify that a business exists and understand where and how it operates. Accuracy and consistency are important, particularly for businesses that move, change phone numbers, rebrand, merge locations, or operate multiple locations.

Not every directory is valuable. Businesses should prioritize authoritative, relevant, and locally meaningful sources rather than submitting information to hundreds of low-quality directories.

Citations are one component of local SEO, along with the website, Google Business Profile, reviews, local content, links, and geographic relevance.

Broken link building is a link-earning tactic that identifies links on other websites pointing to pages that no longer exist, then offers a relevant working resource as a potential replacement. It can help publishers repair a poor user experience while creating an opportunity for the replacement resource to earn a backlink.

The process typically involves finding relevant broken external links, understanding what the missing resource originally provided, identifying or creating a genuinely useful substitute, and contacting the website owner with the correction.

Success depends on relevance and usefulness. Simply finding a broken link does not make an unrelated page an appropriate replacement, and mass automated outreach often produces poor results.

Broken link building is one of many possible approaches within a link-building strategy. See what link building is and what a backlink is for the underlying SEO concepts.

Duplicate content is identical or substantially similar content available at more than one URL, either within the same website or across different websites. Duplicate content can occur intentionally or through technical conditions such as URL parameters, filtered pages, HTTP/HTTPS versions, copied product descriptions, or multiple paths to the same content.

Duplicate content is not automatically a penalty. The SEO concern is that search engines may need to determine which version should be indexed and ranked, and ranking signals may become divided among competing URLs.

Common solutions include consolidating redundant pages, using canonical URLs, implementing appropriate 301 redirects, improving internal linking, and preventing unnecessary duplicate URLs from being generated.
